2D Cylinder Flow

Introduction

Around this time last year, I spent two months working on a simulation of a two-dimensional cylindrical wake using PINNs. I hadn’t finished working on this article. This time, since I built a new Python development environment, I decided to tackle this theme as an example project, with Claude as my companion.

Introduction

Two months ago in this post, laminar flow around a 2D circular cylinder (Laminar Flow), using the governing equations for each of the ST and VP forms, The simulation was performed using the governing equations for each of the ST form and VP form.

Since then, we have simulated the flow around a 2-D cylinder in the time range 0 to 60 seconds for various parameters, and the results are summarized here.
